Technical field
The utility model relates to a kind of ship power propulsion device, especially a kind of emergency roll-setting gear.
Background technique
Pitch propeller device can pass through adjusting under conditions of not changing propeller shaft steering by electric remote control, hydraulic-driven
The blade angle of pitch changes the thrust size and Orientation of paddle, the power of host is converted to the thrust to ship, so that naval vessel be made to realize
The operating conditions such as positive boat, boat, parking and speed of a ship or plane control or manoeuvre.
When full ship power loss, tuning for Controllable Pitch Propeller hydraulic system all lose function or pitch propeller device breaks down, tuning for Controllable Pitch Propeller
Device will be unable to carry out normal roll adjustment, influence the vitality of whole ship.Currently, it is domestic mainly using hand pump or air driven pump to
The mode that the propeller hub oil cylinder of pitch propeller device carries out oiling realizes emergency roll adjustment.It is needed using the method by means of hydraulic system,
And the emergency roll adjustment of " hydraulic-driven " mode is realized by propeller hub oil cylinder.It is different from traditional emergency roll adjustment mode, does not need to borrow
Hydraulic system and propeller hub oil cylinder are helped, the emergency roll adjustment of " Mechanical Driven " mode is realized, can also equally solve pitch propeller device in pole
The predicament of roll adjustment can not be carried out in the case of end.
Summary of the invention
The utility model is to provide for a kind of mechanical emergency roll-setting gear, and roll-setting gear can be transformed into spacing paddle
State uses, and to guarantee the navigation of ship in extreme circumstances, and is suitable for ship power propulsion system pitch propeller device.
To achieve the above object, the technical solution of the utility model is: a kind of mechanical emergency roll-setting gear, including lining
Set, emergency oil cylinder, outer oil pipe, the seal with buss are fixedly connected in the axis of stern end, and the cylinder body of the emergency oil cylinder is arranged in stern
It holds in the front of shaft end, sealing is slidably connected the piston bush in cylinder body in bushing, and between piston and bushing, and outer oil pipe is placed in stern
It holds in axis and bow end axis, the outer oil pipe in stern end axis and bow end axis is linked together by forward and backward ring, the outer oil pipe in the axis of stern end
It is inserted in piston, is provided with pouring orifice on the axis of the stern end；Pouring orifice connection emergency oil cylinder is located at the oil pocket at the nearly stern end of piston.
Further, it is equipped with the second sealing ring between the piston and bushing, is equipped between piston and the cylinder body for oil cylinder of meeting an urgent need
Third sealing ring is equipped between the axis inner hole at the first sealing ring, bushing and stern end.
Further, the emergency oil cylinder is equipped with safety valve.
Further, the pouring orifice connects air driven pump.
Further, the outer oil pipe and rear piston rod and the rigid connection of rear piston in propeller hub.
The beneficial effects of the utility model are:
The emergency roll adjustment that " Mechanical Driven " mode is realized using emergency set, can be in full ship power loss, tuning for Controllable Pitch Propeller hydraulic pressure system
Under system all loses function or pitch propeller device breaks down equal extreme cases, blade screw pitch is adjusted to full ahead pitch
Position, to promote the Emergency use performance of pitch propeller device.
Detailed description of the invention
Fig. 1 is the mechanical emergency roll-setting gear structure sectional view of the utility model；
Fig. 2 is the mechanical emergency roll-setting gear schematic three dimensional views of the utility model；
Fig. 3 is the mechanical emergency roll-setting gear general illustration of the utility model.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of mechanical emergency roll-setting gear 20, is installed in axis.The device includes safety valve
1, the first sealing ring 2, piston 3, the second sealing ring 4, third sealing ring 5, bushing 6, screw 7, pouring orifice 8, emergency oil cylinder 9, outer
Oil pipe 10 etc..
Bushing 6 is fixed in the axis of stern end by screw 7, and the cylinder body of emergency oil cylinder 9 is arranged in the shaft end front of stern end, cylinder body
In 3 sets of piston in bushing 6.Between piston 3 and bushing 6 be equipped with the second sealing ring 4, piston 3 and emergency oil cylinder 9 cylinder body it
Between be equipped with the first sealing ring 2, third sealing ring 5 is equipped between 13 inner hole of bushing 6 and stern end axis.Oil cylinder 9 of meeting an urgent need is equipped with safety
Valve 1, for protecting related machinery.Pouring orifice 8 is provided on stern end axis 13, and the connection emergency oil cylinder 9 of pouring orifice 8 is located at piston 3
The oil pocket at nearly stern end.Pouring orifice 8 connects air driven pump 16.
By adjusting the connection of axis 15 between stern end axis 13 and bow end axis 14, stern end axis 13 and bow end axis 14 are built-in with outer oil pipe
10, the outer oil pipe 10 in stern end axis 13 and bow end axis 14 is linked together by forward and backward ring 11,12, and at forward and backward ring 11,12
In in adjustment axis 15.Rear piston rod 18 and rear piston 19 in outer oil pipe 10 and propeller hub 17 are rigidly connected.
Before carrying out emergency roll adjustment, piston 3 is in left stern Xiang Duanwei.In use, pouring orifice 8 injects from axis by air driven pump
Pressure oil, push piston 3 move right bow to, after 3 top outer oil pipe of piston after ring, under the action of high pressure oil, piston 3 after
It is continuous push after outer oil pipe ring together with entire outer oil pipe move right bow to.Since outer oil pipe is lived with the rear piston rod in propeller hub and afterwards
Plug rigid connection, after also being driven while outer oil pipe is mobile piston move right bow to.By the movement of piston 3, propeller hub is driven
